Check Digit Verification of cas no

The CAS Registry Mumber 54125-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,1,2 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 54125-23:
(7*5)+(6*4)+(5*1)+(4*2)+(3*5)+(2*2)+(1*3)=94
94 % 10 = 4
So 54125-23-4 is a valid CAS Registry Number.

Ligand-Assisted Catalysis: New Active and Selective Nickel Modified Homogeneous Catalysts for Linear Dimerization of Butadiene

Denis, Philippe,Mortreux, Andre,Petit, Francis,Buono, Gerard,Peiffer, Gilbert

, p. 5274 - 5276 (2007/10/02)

New aminophosphinite-modified Ni(0) catalysts have been found to be the most active ever described for linear dimerization of butadiene, affording almost exclusively 1,3,6- and 2,4,6-octatrienes, according to the reaction conditions.
